Abstract

There is described a sensor device for spectrally resolved capture of optical detection radiation which emanates from a value document transported through a capture area of the sensor device in a predefined transport direction, comprising a detection device for spectrally resolved detection of the detection radiation in at least one predefined spectral detection range and emission of detection signals which represent at least one, in particular spectral, property of the detected detection radiation, at least one reference radiation device which emits optical reference radiation which is coupled into a detection beam path of the detection device at least partly in dependence on the position of a value document relative to the capture area, and which has a spectrum with a narrow band which is within the predefined spectral detection range, and/or at least one spectrum with an edge which is within the predefined spectral detection range, and a control and evaluation device which is configured for employing the detection signals which represent the property of the reference radiation, for checking and/or for adjusting the detection device and/or in the evaluation of detection signals w…
